The coronary lithotripsy system is indicated when there is a need to improve the lumen of calcified and stenotic coronary arteries with a balloon catheter under low ATM before a stent is implanted. (1) The coronary intravascular lithotripsy catheter is routed through coronary arteries until it reaches a difficult to approach spot of a calcified stenosis, including also the calcified stenosis that we assume are going to provide resistance when being inflated by a PTCA balloon or when a coronary artery is being prepared for a stent implantation and evenly expand an implanted coronary stent. The lithotripsy catheter emits intermittent sound waves at the aimed spot, breaking the calcium clusters in the lesion therefore enabling a larger lumen with the help of a low ATM inflated balloon.

In this paper we will present a case report of a patient before and after intravascular lithotripsy, including the preparation of the patient and the catheter itself.
